The father-son reunion may have been recent as Martin returned stateside after his band performed at the Global Citizen Festival in Mumbai for their first-ever concert in India. Also at the festival was Paltrow and Martin’s close friend Jay Z.

In June, Paltrow said in an interview in Cannes that her divorce was “difficult” but she was happy they’ve been able to amicably co-parent.

“As anybody who has been divorced knows, you have to put a lot aside to maintain the family and the practicalities of what that might mean and sometimes that’s quite tough on a personal level,” Paltrow explained, adding, “It’s a commitment I make every day to my children and their father even though we’re not in a romantic relationship.”
